A concrete surface chisel machine

Abstract

The invention discloses a concrete surface bush hammer. The concrete surface bush hammer comprises a casing (1) in one side of which an opening is formed, and a cover plate (2) arranged on the opening side of the casing (1), wherein a dual-output shaft motor (3) is arranged in the casing (1); a connecting rod mechanism is fixedly mounted at each of the output shaft ends of the dual-output shaft motor (3); a drive block (4) in rotary connection fit with the connecting rod mechanism is arranged at the other end of the connecting rod mechanism; two sides of the other end of the drive block (4) respectively extend outwards to form upper positioning seats (41) and lower positioning seats (42); the two upper positioning seats (41) are in rotary connection fit with an upper driving seat (5); and the two lower positioning seats (42) are in rotary connection fit with a lower driving seat (6). The concrete surface bush hammer disclosed by the invention is simple in structure and convenient to use; and because the bush hammer is small in overall volume and can enter narrow spaces for chiseling, any limitation existing in the using process is avoided.

Description

technical field [0001] The invention relates to the field of processing and manufacturing construction electric appliances, in particular to a concrete surface chisel machine. Background technique [0002] In order to facilitate the construction during construction, the method of segmented construction is usually adopted. In order to improve the bonding strength between the segments, the surface of the upper segment needs to be roughened before pouring, so as to make the concrete bond more firmly. However, most of the current common chisel methods still rely on manual work, which is not only labor-intensive but also low in efficiency. In order to solve this problem, a chisel machine has appeared on the market, which mainly deals with large Plane chiseling, for the chiseling at the roots of walls and columns, it is often difficult to enter the construction due to the limitation of the reserved vertical steel bars, and there are strong limitations and scope of application.
